Brief Introduction
Refractory Ramming mass is a refractory material made by ramming process. It is composed of various aggregates, binders and additives. We supply different types of ramming mass, including acidic ramming mass, neutral ramming mass and basic ramming mass, as follows:
Rongsheng acidic ramming mass: silica ramming mass and quartz ramming mass, etc.;
Rongsheng neutral ramming mass: corundum ramming mass, mullite ramming mass and aluminum ramming mass, etc.;
Rongsheng basic ramming mass: dolomite ramming mix, magnesia ramming mass, magnesia aluminum ramming mass and aluminum magnesia ramming mass, etc.;
